Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the city car segment and utilize the same 5-door hatchback body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Daihatsu-engineered powertrain under the hood, a 4-cylinder, 16-valves 91hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 86hp engine designed by Toyota.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Toyota being a slightly better choice apparently. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, Yaris offers a marginal difference of 8% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Daihatsu does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Daihatsu with an average rating of 4.1, and models under the Toyota badge with 4.6 out of 5. Some independent research have also placed Sirion as average reliability-wise, and Yaris is more or less at the same level.That apart, owners of different cars powered by the same engine as Sirion rank it on average as 5.0 out of 5, exactly the same as the other one.

Daihatsu is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 170 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle.

Daihatsu appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, Yaris offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Daihatsu offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
